View source for Spectral estimates and identifying the inertial subrange

This is a placeholder that could list processing steps applied from level 2 to level 3, i.e. computing spectra and identifying whether there's an inertial subrange at all... We could perhaps drag in estimating epsilon from the spectra too here.

* [[Estimate epsilon|estimated <math>\varepsilon</math>]] using stats
